A partnership built for progress

The delivery of the 50th PureBallast™ system to Damen Cargo Vessels marks a significant moment in a partnership defined by shared values and long-term vision. Since 2023, the collaboration has focused on integrating sustainable technologies into Damen’s Combi Freighter series - vessels designed for short sea shipping in Northwest Europe.

The partnership combines Damen’s shipbuilding expertise with Alfa Laval’s ballast water treatment innovation, supported by a global service network and local production in Qingdao. Together, the companies deliver vessels that meet regulatory demands while contributing to cleaner oceans.

Responding to market needs

The European cargo fleet is undergoing a generational shift. Ship owners are replacing aging vessels with modern, efficient, and regulation-compliant alternatives. Damen’s Combi Freighters, equipped with PureBallast™, are at the forefront of this transition. This milestone is not just a number – it is a signal of where the industry is headed: towards integrated, sustainable solutions that deliver long-term value.

Technology that enables sustainability

PureBallast™ 3.5 plays a key role in supporting Damen’s sustainability goals. The system offers high biological disinfection performance in all water types - fresh, brackish, and marine - without the use of chemicals. Its compact footprint and modular design align with Damen’s engine room configurations and construction philosophy. The latest iteration of PureBallast™, developed in close collaboration with partners like Damen, is optimized for easy installation, digital integration, and low energy consumption, making it a future-ready solution for newbuild vessels.

We are proud to be part of Alfa Laval’s development roadmap. PureBallast™ fits perfectly with our strategy for sustainable, low-maintenance engine rooms." - Jason Bronscheer, Managing Director Damen Cargo Vessels

Impact beyond compliance

The collaboration between Alfa Laval Benelux and Damen Cargo Vessels delivers measurable benefits for ship owners and the environment. Operational data shows significant reductions in fuel consumption and emissions, while the chemical-free nature of PureBallast™ supports marine biodiversity protection.

20–30% lower operational expenses compared to older vessels
Zero chemical discharge into marine ecosystems
Reduced emissions and energy use through optimized vessel and system design
Global service support for long-term reliability

These results reflect the value of integrating sustainable design and proven technology from the outset.

We’re shaping the future of clean shipping together moving from retrofits to newbuilds, and from compliance to true sustainability.” - Anna Wielander, PureBallast™ Product Owner

Looking ahead

With a strong foundation and a shared roadmap for innovation, Alfa Laval and Damen Cargo Vessels are committed to continuing their journey - delivering sustainable, high-performance vessels that meet the evolving needs of the maritime industry. The milestone of 50 deliveries is not a conclusion, but a launchpad for the next phase of collaboration.
